Android 列表项在listview中的位置不正确

我正在制作一个应用程序，其中我需要一个列表视图来显示任务列表。这是一个基于位置的提醒应用程序。但在列表视图中，每当我向列表中添加一项（任务）时，它都会出现在底部。 我的意思是，我希望第一个项目被添加到列表的顶部，但它会出现在底部。那么，有什么帮助吗

下面是列表的内容：

list:




first item 
second item

以下是我想要的：

list:
first item 
second item


..

以下是设置适配器和listview的代码：

    ArrayAdapter <String> adapter;

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);

        lv = (ListView) findViewById(R.id.listView1);
        mydatabase = openOrCreateDatabase("seproject", MODE_PRIVATE, null);
        Cursor cursor = mydatabase.rawQuery("Select * from Store", null);

        final ArrayList<String> list = new ArrayList<String>();
        int i = 0;

        if (cursor != null && cursor.getCount() > 0) {

            cursor.moveToFirst();

            do {
                String s= cursor.getString(0);

                list.add(cursor.getString(0));

                lat[i] = Double.parseDouble(cursor.getString(1));
                longt[i++] = Double.parseDouble(cursor.getString(2));


            } while (cursor.moveToNext());
            mydatabase.close();

        }
 Collections.reverse(list);  //Kept this here. It worked. 
        adapter  = new marrayadapter(this,list);
        lv.setAdapter(adapter);

                                    int position, long id) {
                // TODO Auto-generated method stub


                CheckedItem = (position);

            }


        });


        button = (Button) findViewById(R.id.button2);
        button.setOnClickListener(new OnClickListener() {
            @Override

                  Toast.makeText(Second.this, "Deleted", Toast.LENGTH_LONG).show();
                 mydatabase.close();
                 /* Intent i = new Intent(Second.this, Second.class);
                  startActivity(i);

                  list.remove(CheckedItem);
                  adapter.notifyDataSetChanged();



                  }
              catch (Exception e)
              {
                  Toast.makeText(Second.this,"No tasks to delete.", Toast.LENGTH_SHORT).show();
              }



            }
        });
        button2 = (Button) findViewById(R.id.button1);

    @Override

        getMenuInflater().inflate(R.menu.second, menu);

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.

        switch (item.getItemId()) {

在设置适配器之前，将

集合。反转
功能移到
列表上：

Collections.reverse(list);  
adapter  = new marrayadapter(this,list);
lv.setAdapter(adapter);

您需要在第0个索引处添加列表项，
list.add（0，cursor.getString（0））

试试这个..
那么你想做什么？我希望列表在listview中按顺序排列。我的意思是，添加的第一项应该在列表的顶部，但它在底部。只有一个解决方案使用了
自定义适配器
我使用了自定义适配器。（参见代码中的“marrayadapter”）。请参见我更新的问题。抱歉不清楚，我是新手。请看我的最新问题。抱歉不清楚，我是新手。请看我的最新问题。抱歉说不清楚，我是新手。
Collections.reverse(list);  
adapter  = new marrayadapter(this,list);
lv.setAdapter(adapter);

int index = this.list.getFirstVisiblePosition() + list.size();
View v = this.list.getChildAt(list.getHeaderViewsCount());
int top = (v == null) ? 0 : v.getTop();         

this.adapter.AddRangeToTop(comments);
this.adapter.notifyDataSetChanged();    

this.list.setSelectionFromTop(index, top)
